Alectrona
Commercial solar by areaYorkshire-based and quick to your site across Grimsby and North East Lincolnshire, designing commercial solar above 50 kWp for the town's seafood-processing plants, cold stores and South Humber Bank industry. We have not installed in Grimsby yet, so we lead with an on-site drone survey and a load-matched design, not a local job count we cannot evidence.
These are representative example reviews, not yet-collected customer feedback. They are written to illustrate the kind of feedback Alectrona aims to earn and are shown as design placeholders while we gather and verify reviews from our first commercial clients. Alectrona is the commercial solar trading brand of RVTC LTD.
What set Alectrona apart was the documented design pack. We had quotes from three installers, but only Alectrona handed us a full set of drawings, a single-line diagram and a design referencing BS 7671 and the G99 connection process. The whole thing read like an engineering submission rather than a sales brochure. Our M&E consultant reviewed it and signed it off without a single query. That gave the board the confidence to release the capital.
Other firms priced our roof off a satellite image and a desktop guess. Alectrona flew an in-house drone survey, fully insured and flown by a qualified commercial drone pilot, and built a 3D model of the actual roof. It picked up plant, vents and a parapet line that a flat aerial photo had completely missed, which changed the panel layout. I would rather find that out at design stage than on the day the scaffold goes up. The accuracy of that survey is the reason I trusted everything that followed.
As a finance director I was wary of being oversold a system bigger than we could use. Alectrona modelled the array against our actual half-hourly consumption data rather than an annual total, so it is sized to what we genuinely draw on site during the day. They were honest that exporting surplus is worth far less than self-consumption, and built the design around that. The capital case stacked up because the engineering was honest, not because the numbers were inflated.
We were undecided between buying outright, leasing and a PPA. Alectrona laid out all three side by side with the pros and cons of each against our balance sheet, instead of pushing the one that pays them best. They were clear about where a PPA makes sense and where capex wins, and pointed us at our own accountant for the tax treatment. The survey and design took a little longer than I expected, but the thoroughness was worth the wait. Genuinely consultative.
The install crew were tidy and well run, and worked to a clear CDM 2015 plan with a proper site induction and RAMS. What impressed me most was the handover. We received a full commissioning pack with the IEC 62446-1 test results, certification, O&M documentation and an as-built record for our maintenance team. As the people who have to live with this asset for the next twenty years, having that paperwork in order matters enormously. Nothing was left loose.
I expected the usual hard sell and got the opposite. After surveying our site Alectrona told us one roof section was not worth covering because of shading, and that a smaller, well-sited array was the better investment than filling every square metre. There was no commission-driven upselling and no pressure. For a six-figure capital project, that straight talk is exactly what you want from the people advising you. We will be using them again on our second site.
Grimsby runs one of the most refrigeration-heavy commercial economies in the country, and that is exactly the demand profile rooftop solar pays back against. Alectrona is the commercial arm of RVTC LTD, Yorkshire-based and working across the Grimsby DN postcode districts, from the DN31 town centre and the DN37 Pyewipe estate out to Laceby, Healing and the south Humber bank. We are honest from the start: we hold no completed installs in the town yet, so this page is about coverage, the engineering a system this size demands, and the survey we bring, not a local track record.
A system over 50 kWp sits outside the domestic MCS route and carries real structural, electrical and grid-connection weight. On a Grimsby cold store or processing unit the array can run to several hundred kilowatts, so the roof loading, the inverter strategy and the G99 connection are all engineered against the building's real half-hourly demand before anyone quotes a panel count. Every enquiry starts with an in-house insured drone pilot flying the actual roof and a PV*SOL model built against your own load.
Grimsby's commercial roof stock is built around food. The town is the largest seafood-processing cluster in Northern Europe, with something approaching 6,000 people working directly across 65 or more factories, and roughly 70 per cent of the UK's seafood passing through the town. That cluster is concentrated at Europarc, the flagship business park off the A180 at Pyewipe in the DN37 district, home to the Humber Seafood Institute, and across the wider processing belt. Names associated with the town, including Young's Seafood, Hilton Seafood UK, New England Seafood and Espersen, describe the kind of occupier here rather than any customer of ours. The point for a solar design is the load underneath those roofs: chilled and frozen process plant runs compressors, blast freezers and packing lines through the working day, a flat, high daytime demand that an array generates straight into, so most of the output is consumed on site at the meter rather than exported.
The buildings themselves suit the work. Across Europarc, Pyewipe and the South Humber Bank the stock is dominated by large single-storey portal-frame cold stores, seafood-processing units, food factories and distribution sheds, broad flat and low-pitch roofs with the deck area a substantial array needs. East along the Stallingborough corridor towards Immingham, the South Humber Bank carries heavier process, chemical and energy industry on designated Enterprise Zone and industrial-park sites, and the port-centric Grimsby Future Park and the local Food Enterprise Zone are bringing forward further manufacturing and low-carbon plots. The Port of Grimsby, run by Associated British Ports alongside Immingham as part of the UK's largest port complex by tonnage, is also the world's largest offshore-wind operations and maintenance hub, with RWE's Grimsby Hub running the Triton Knoll and Sofia wind farms, which adds maintenance, warehousing and quayside roofs to the mix.
Each of those load shapes is modelled on its own metered data, not a single Grimsby template. A continuous cold store wants a different sizing decision from a daytime processing line or a port warehouse, and that is the work the survey and the half-hourly data settle before anything is sized.
Every Grimsby design starts with an on-site survey, not a satellite estimate. Our in-house drone pilot, fully insured and qualified to A2 CofC and GVC standard, flies a 3D survey of the roof, capturing pitch, orientation, shading, plant and the true usable area. That model feeds a PV*SOL simulation run against your half-hourly consumption, so the array is sized to what the building actually draws across the working day.
The survey travels to Grimsby exactly as it does anywhere in Yorkshire. Whether the roof is a Europarc cold store at Pyewipe, a seafood-processing unit in the DN31 town belt or a distribution shed along the South Humber Bank, the pilot comes to you and the design is built from what the drone records on the day.
The distribution network operator for Grimsby and the south Humber bank is Northern Powergrid, under its Northeast and Yorkshire licence, and any system over 50 kWp connects under a G99 application to them. Grimsby sits towards the edge of Northern Powergrid's territory, with the local network connecting to transmission at the Grimsby West grid supply point, so while the operator is correct for the town we confirm the specific connection point, MPAN and grid supply point for the actual site before quoting connection terms, rather than assuming them. The outer DN36 and DN37 sectors in particular reach into surrounding North East Lincolnshire settlements, so the site address alone does not settle the position.
On the heavy, self-consumed refrigeration loads that define the town's processing and cold-store roofs, the connection is often more manageable than the headline kWp suggests, because much of the generation never leaves the building. Where the network needs it, a G99 export-limitation scheme lets the array run at full output for self-consumption while capping what reaches the grid. We prepare and manage the application and the export-limitation engineering as part of the project rather than handing it to you.
Grimsby and the wider South Humber bank hold a real number of commercial arrays from the Feed-in Tariff years, much of it on processing and distribution roofs built out between roughly 2012 and 2016 and now running on ageing inverters with little or no monitoring. Through our sister operation Solar Tech Support we take on independent, brand-agnostic operation and maintenance and the takeover of those older systems, whoever installed them and whatever brand sits on the roof, with monitoring, fault-finding, inverter and string work and cleaning to keep an inherited array earning.
The town's location adds a maintenance factor worth naming. Roofs close to the Humber estuary and the dock estates sit in a salt-laden coastal atmosphere, which builds soiling faster than an inland site and feeds into the cleaning schedule and the fixing specification. We set the maintenance scope against the actual site rather than publishing a fixed response time we cannot stand behind, and we will tell you honestly what an older array is producing against what it should.

Not yet, and we say so plainly. We are Yorkshire-based and cover Grimsby and North East Lincolnshire, but we have not installed in the town to date, so we make no claim of a local track record. What we bring is coverage of the area, the engineering capability for systems over 50 kWp, and an in-house drone survey that comes to your roof like anywhere else we work.
Chilled and frozen process plant runs compressors, blast freezers and packing lines through the working day, a flat, high daytime load that matches solar generation closely. That means most of the array's output is consumed on site behind the meter rather than exported, which is where the strongest return on a commercial system comes from. We confirm the fit by modelling the array against your own half-hourly data across Europarc, Pyewipe and the South Humber Bank.
The distribution network operator for Grimsby and the south Humber bank is Northern Powergrid, and a system over 50 kWp connects under a G99 application we prepare and manage. Grimsby sits near the edge of Northern Powergrid's territory, with the local network feeding off the Grimsby West grid supply point, so we confirm the specific connection point and grid supply point for your site before quoting connection terms. Where export headroom is tight, a G99 export-limitation scheme keeps the system within the network's limits while you still self-consume the generation.
Yes. Through Solar Tech Support we provide independent, brand-agnostic operation and maintenance and take over older FiT-era arrays across Grimsby and the South Humber bank, whoever installed them, with monitoring, fault-finding, inverter work and cleaning. On roofs close to the Humber estuary we plan a scheduled clean and inspection, because salt-driven soiling builds faster near the dock estates than inland. We agree the scope against the site rather than quoting a fixed response time we cannot stand behind.
We do not publish a price or a from-figure, because a system over 50 kWp is costed from the survey rather than a per-roof rate. The figure comes from the drone survey and the PV*SOL model built against your half-hourly demand, not a per-mile charge or a headline number, and on a heavy refrigeration load like a Grimsby cold store the array can run to several hundred kilowatts, which changes the engineering and the cost. What sets the number is the usable roof area, the structural and fixing specification, the inverter strategy, the G99 connection to Northern Powergrid and any export-limitation work, plus whether storage strengthens the case. We survey the actual building first and cost it against what we find, the same approach we take anywhere in Yorkshire, so the quote reflects your roof and your load rather than a template. The return is driven by self-consumption against that steady daytime processing demand, which is why we model the load before we size anything.
Quickly, because we are Yorkshire-based and Grimsby and North East Lincolnshire are within our normal coverage rather than a special trip. The drone survey comes to your roof at Europarc, Pyewipe, the DN31 town belt or the South Humber Bank the same as anywhere else we work, and a site visit is part of standard coverage. The programme after that is set mainly by the G99 connection process with Northern Powergrid, not by travel time. A system over 50 kWp needs the export position confirmed for your specific point of connection near the Grimsby West grid supply point, and that DNO timeline, alongside any structural and procurement lead times, drives the schedule more than how far we have to drive. We give you an honest programme once the survey and the connection position are settled, rather than promising a fixed turnaround we cannot stand behind before we have seen the roof and the grid answer.
Wherever you are in the region, the on-site drone survey comes to you and the PV*SOL model sets the figure. Send us the site and the half-hourly load, and we will come back with a designed system.
